I received this recording without a month, day, or venue. However since another recording on archive.org https://archive.org/details/Ae2001-05-09.flac16 has this show listed at the Opera House and on this date - and I doubt that Autechre came to Toronto twice. It could be possible they played there two nights in a row or something and this date / info is incorrect. The recording I've uploaded seems to have a different source than the other one here on archive.org. The second half of the recording I have uploaded is blank (no sound), however it is unlikely they played more than an hour so this upload probably has everything.
If you have more info about this recording I've uploaded, please share.
